Solution Overview

Problem

Wearable devices, particularly VR housings, face a challenge with high weight due to the use of injection molded materials or carbon fiber composite structures, which diminish user experience.

Innovation Solution

A housing for smart head mount devices is constructed using a weight-reducing frame made of organic aerogel material with a density of 0.4 g/cm3 to 1.3 g/cm3 and a bending modulus greater than 2.5 GPa, optionally combined with auxiliary supporting parts and reinforcing materials like engineering plastics or lightweight alloys.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If injection molded materials or carbon fiber composite structures are used for VR housing, then high strength is achieved, but weight increases significantly

Engineering Contradiction:

Improvehousing strengthVSAvoidhousing weight

Core Design Contradiction:

StrengthVSWeight of moving object

Solution Approach 1:

The patent applies porous materials (aerogel and foam materials) to create a lightweight housing structure. The porous structure reduces material density while maintaining structural integrity through the framework design, achieving weight reduction while preserving necessary strength properties.

Inventive Principle:

Principle #31Porous materials

Solution Approach 2:

The housing is divided into a frame structure rather than a solid monolithic structure. This segmentation allows the use of lightweight porous materials while maintaining strength through the strategic arrangement of structural elements, resolving the contradiction between weight and strength.

Inventive Principle:

Principle #1Segmentation

2Weight of moving object

If aerogel material is used to reduce weight, then weight decreases, but manufacturing complexity increases

Engineering Contradiction:

Improvehousing weightVSAvoidmanufacturing ease

Core Design Contradiction:

Weight of moving objectVSEase of manufacture

Solution Approach 1:

The patent specifies parameter ranges for the aerogel material (density of 0.4-1.3 g/cm³, bending modulus >2.5 GPa) to balance weight reduction with manufacturability. By defining specific parameter ranges, the patent makes the use of complex aerogel materials more controllable and manufacturable.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent combines aerogel or foam materials with reinforcing materials to create a composite structure. This composite approach allows the use of lightweight porous materials while adding reinforcement to maintain structural integrity and improve manufacturability.

Inventive Principle:

Principle #40Composite materials
